“Taku Sugawara is the devil. Nobody should believe his words.”

Victoria received a marriage certificate when she was about to be proposed to by her boyfriend. The marriage certificate showed that she had married a stranger two years ago. The stranger was a CEO who was known to be a perfectionist and arrogant named Matthias. What actually happened? Why couldn't she remember anything that happened two years ago due to an accident? What was on her mind now was that she really hated Matthias because all her dreams were destroyed in an instant and she was trapped in a marriage that she didn't want.Meanwhile, Matthias deliberately sent the marriage certificate to Victoria so that his woman's engagement to another man would be canceled. Matthias didn't know how Victoria could suddenly leave him two years ago. When he investigated the case of his wife's sudden disappearance, he just found out that his wife disappeared because of an accident that was deliberately hidden by his wife's adoptive family and her family. Matthias suspected that Victoria's accident was the result of evil deeds carried out by both families. Therefore, he decided to win Victoria's heart back even though Victoria hated him so much that she cursed him as the cruelest man who hindered her dreams. Because their relationship before the accident was very harmonious and they already loved each other.However, behind the hatred that was buried in Victoria's heart, every time she looked at the CEO's handsome face, she always wanted to cry. Who was Matthias's real identity? Then, why was Matthias so obsessed with her even though they had never met? In order to be free from her unwanted marriage and return to her boyfriend, she made a marriage contract with Matthias. If Matthias failed to win her heart for three months, then they had to divorce and had no right to have any contact with each other anymore. This actually made Matthias even more confident in wanting to win his wife back. Even though they always misunderstood each other, he still loved Victoria and wanted to take revenge on everyone who wanted to destroy their relationship two years ago.
